Abstract

This paper presents further results from a longitudinal research study that has been conducted
with one organization, the Western Financial Services (WFS) Group, over a six-year period
(Barry 2004). They operate in the financial services sector and rely heavily on information
systems (IS) and information technology (IT). In the early years from 1986 to 1997 the firm
ran its IS/IT function in a manner that responded to business events rather than implementing
a co-ordinated, planned strategy. Despite the fact that the financial services it operated were
supported by information systems, critical to the orderly operations of the firm, WFS have
always been a ¿lean¿ and flexible organization, growing structures organically. While the
general posture toward IS/IT investment might appear as a pragmatic and sensible approach
(Earl 1992), the reality is that under-investment in IS/IT capacity and resources meant that
flexibility and responsiveness were never achieved. Each new project appeared to start from
scratch and little organizational learning was being retained or disseminated. The episodic
flurry of urgent requirements at WFS for an information system, contrasts significantly with
the normative, structured approach to information systems development (ISD), so dominant in
the past and outwardly at least at the present time. However other approaches such as problem
structuring methods - PSMs (Rosenhead & Mingers 2001), may appear to offer a more
realistic assessment of how systems requirements should be gathered. These methods inject a
definitive role for people, intimately involved in the development process and usage of the
final system. A third, less widely known, approach - the amethodical view - has been put
forward more recently (Introna & Whitley 1997, Ciborra 1999, Truex, Baskerville & Travis
2000). It suggests that IS are developed improvisationally and amethodically. An alternative
perspective, identifying some problems with the nature of support and analysis of the above
approaches (Barry 2005), posits that much can be understood by examining the occurrence of
incremental decision-making within the ISD process. This is illustrated within a framework
combining differing decision-making styles, the actors involved and the various stages of
ISD. The findings of this research suggest that this latter perspective can represent a richer
picture of the complexity, and often the messiness, of the systems development process. With
this in mind the work presented herein signifies the researcher¿s reflections about three
information systems projects within the same organization, in which he played an involved
role. The projects differ in size, scope and their relative importance.
